This is due to the function not verifying that the user has `edit_others_posts` capability before accepting a `selectedAuthorId` parameter via the `duplicate-post` REST endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicated posts attributed to any user, including administrators."}], "lastModified": "2026-08-24T16:41:13.950", "sourceIdentifier": "security@wordfence.com"}
